739-739: Consider implementing the standard equality pattern.For a complete and consistent equality implementation, consider:
- Overriding
Object.Equals(object)- Implementing
IEquatable<VariableBase>- Overriding
GetHashCode()- Implementing equality operators (
==and!=)This ensures symmetric equality behavior and follows .NET best practices.
Here's a suggested implementation:
+ public override bool Equals(object obj) + { + return AreEqual(obj); + } + + public override int GetHashCode() + { + return HashCode.Combine(Name, VariableType, GetInitialValue()); + } + + public static bool operator ==(VariableBase left, VariableBase right) + { + if (ReferenceEquals(left, null)) + return ReferenceEquals(right, null); + return left.AreEqual(right); + } + + public static bool operator !=(VariableBase left, VariableBase right) + { + return !(left == right); + }Ginger/GingerCoreCommonTest/EqualityTests/BusinessFlowTests.cs (1)
40-61: Consider separating test data creationThe
CreateBusinessFlowhelper method creates complex objects with Activities, Variables, and TargetApplications, but the current tests only verify name equality. Consider:
- Simplifying the helper for basic tests
- Creating separate helpers for complex scenarios
Example refactor:
private BusinessFlow CreateSimpleBusinessFlow(string name) => new BusinessFlow { Name = name }; private BusinessFlow CreateComplexBusinessFlow(string name) { var flow = CreateSimpleBusinessFlow(name); flow.Activities = [/* activities */]; flow.Variables = [/* variables */]; flow.TargetApplications = [/* applications */]; return flow; }Ginger/GingerCoreCommonTest/EqualityTests/ActivityTests.cs (1)
11-40: Consider adding null checks to AreEqual_SameProperties_ReturnsTrue testThe happy path test uses non-null values for all properties. Consider adding a variant that tests equality with null values for optional properties.
Example:
[TestMethod] public void AreEqual_SamePropertiesWithNulls_ReturnsTrue() { // Arrange var activity1 = new Activity { ActivityName = "Test", TargetApplication = null, Type = eSharedItemType.Regular, ActivitiesGroupID = null, Acts = null, Variables = null }; var activity2 = new Activity { ActivityName = "Test", TargetApplication = null, Type = eSharedItemType.Regular, ActivitiesGroupID = null, Acts = null, Variables = null }; // Act var result = activity1.AreEqual(activity2); // Assert Assert.IsTrue(result); }Ginger/GingerCoreCommon/Actions/ActInputValue.cs (3)
242-244: Simplify null check logicThe current null check can be simplified using string.Equals with StringComparison.
-((this.Value == null && string.IsNullOrEmpty(other.Value)) -|| this.Value == other.Value); +string.Equals(this.Value, other.Value, StringComparison.Ordinal);

256-267: Fix incorrect method call in AreEqual(object obj)The method calls
Equalsinstead ofAreEqual, which could lead to inconsistent behavior.-return Equals(obj as ActInputValue); +return AreEqual(obj as ActInputValue);
Add tests for ActInputValue equality comparisons
The codebase lacks specific tests for the equality comparison behavior in ActInputValue class, particularly for the null handling cases. While there are tests using ActInputValue in WebServicesTest.cs and ActInputValuesTest.cs, none of them verify the equality implementation.
Key areas needing test coverage:
- Null value comparisons
- Empty string vs null value comparisons
- Regular value equality comparisons
- Object type checking in AreEqual method

693-699: Improve filename generation with random numbers for better distribution.The change enhances the filename generation logic by using random numbers when sequential numbering exceeds 100 attempts. This helps avoid potential infinite loops and provides better distribution of filenames.
Consider adding a maximum retry limit to prevent excessive attempts, and log a warning when the limit is reached. Example:
if (counter > 100) { + const int MaxRetries = 1000; + if (counter > MaxRetries) { + Reporter.ToLog(eLogLevel.WARN, $"Failed to generate unique filename after {MaxRetries} attempts"); + throw new Exception($"Unable to generate unique filename after {MaxRetries} attempts"); + } counter = Random.Shared.Next(minValue: 101, maxValue: 10000); }Ginger/GingerCoreCommon/Repository/BusinessFlowLib/BusinessFlow.cs (1)

2053-2067: Improve equality comparison with proper linked activities handling.The changes enhance the equality comparison by:
- Simplifying the comparison logic by focusing on essential fields
- Ensuring linked activities are properly loaded before comparison
However, removing the
TargetApplicationscheck might affect scenarios where target applications are relevant for equality.Consider preserving the
TargetApplicationscheck to maintain complete equality comparison:if (other == null || this.Name != other.Name || this.Activities.Count != other.Activities.Count - || this.Variables.Count != other.Variables.Count) + || this.Variables.Count != other.Variables.Count + || this.TargetApplications.Count != other.TargetApplications.Count) { return false; } +// Check if target applications match +for (int i = 0; i < this.TargetApplications.Count; i++) +{ + if (this.TargetApplications[i].Name != other.TargetApplications[i].Name) + { + return false; + } +}Ginger/GingerCoreCommon/Actions/Act.cs (1)

2069-2119: Consider enhancing equality implementationThe current equality implementation could be improved by:
- Implementing
IEquatable<Act>interface for better type safety and performance- Including comparison of other relevant properties like
ReturnValues,FlowControls, etc.- Overriding
Object.Equals()andGetHashCode()for complete equality contractExample implementation:
- public bool AreEqual(Act other) + public class Act : RepositoryItemBase, IAct, IEquatable<Act> + { + // ... existing code ... + + public bool AreEqual(Act other) + { + return Equals(other); + } + + public bool Equals(Act other) + { + if (other == null) + return false; + + if (ReferenceEquals(this, other)) + return true; + + if (this.ActInputValues.Count != other.ActInputValues.Count || + this.Description != other.Description || + this.Platform != other.Platform) + return false; + + // Compare input values + for (int i = 0; i < this.ActInputValues.Count; i++) + { + if (!this.ActInputValues[i].AreEqual(other.ActInputValues[i])) + return false; + } + + // Compare other relevant properties + return this.ReturnValues.SequenceEqual(other.ReturnValues) && + this.FlowControls.SequenceEqual(other.FlowControls); + } + + public override bool Equals(object obj) + { + return Equals(obj as Act); + } + + public override int GetHashCode() + { + var hash = new HashCode(); + hash.Add(Description); + hash.Add(Platform); + foreach (var input in ActInputValues) + { + hash.Add(input); + } + return hash.ToHashCode(); + }

🛠️ Refactor suggestion
Enhance test coverage for BusinessFlow equality
The current tests only verify equality based on the Name property. Consider adding tests for:
- Equality of child collections (Activities, Variables, TargetApplications)
- Edge cases (null values, empty collections)
- Different ordering of child elements
Example test cases to add:
[TestMethod]
public void AreEqual_DifferentActivityOrder_ReturnsTrue()
{
// Arrange
var flow1 = CreateBusinessFlow("TestFlow");
var flow2 = CreateBusinessFlow("TestFlow");
flow2.Activities.Reverse();
// Act
var result = flow1.AreEqual(flow2);
// Assert
Assert.IsTrue(result);
}
[TestMethod]
public void AreEqual_NullActivities_ReturnsFalse()
{
// Arrange
var flow1 = CreateBusinessFlow("TestFlow");
var flow2 = CreateBusinessFlow("TestFlow");
flow2.Activities = null;
// Act
var result = flow1.AreEqual(flow2);
// Assert
Assert.IsFalse(result);
}Also applies to: 26-38

🛠️ Refactor suggestion
Enhance collection equality tests
The current tests only verify collection counts. Consider adding tests for:
- Actual equality of Acts and Variables
- Different ordering of collection elements
- Null vs empty collection scenarios
Example:
[TestMethod]
public void AreEqual_SameActsDifferentOrder_ReturnsTrue()
{
// Arrange
var act1 = new ActDummy { Name = "Act1" };
var act2 = new ActDummy { Name = "Act2" };
var activity1 = new Activity { Acts = [act1, act2] };
var activity2 = new Activity { Acts = [act2, act1] };
// Act
var result = activity1.AreEqual(activity2);
// Assert
Assert.IsTrue(result);
}Also applies to: 112-124
